Effect of solid and liquid organic supplements on yield, physical characteristics and quality of rice

Abstract

Field experiments were conducted during Rabi seasons of 2019 and 2020 (September to January). Medium duration rice cv. white ponni (improved) was used as a test variety at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Killikulam, Thoothukudi District, India. The objective of the research is to study the influence of solid and liquid organic manures (Enriched FYM compost, Enriched poultry manure compost, Enriched FYM compost + 3% Jeevamrutham foliar spray at 30and 45 days after transplanting, Enriched FYM compost + 3% Beejamrutham foliar spray at 30&45 DAT, Enriched FYM compost + 3% Panchagavya foliar spray at 30and 45 days after transplanting, Enriched poultry manure compost + 3% Jeevamrutham days after transplanting at 30 and 45 days after transplanting, Enriched poultry manure compost + 3% Beejamrutham foliar spray at 30 and 45 days after transplanting and Enriched poultry manure compost + 3% Panchagavya foliar spray at 30 and 45 days after transplanting and recommended NPK fertilizers on yield and quality of rice. Based on field experiments, it was found that the application of enriched poultry manure compost + 3% Panchagavya foliar spray at 30 and 45 days after transplanting recorded higher yield attributes and grain yield of rice (4597 kg ha-1 in 2019 and 4953 kg ha-1 in 2020). The application of enriched poultry manure compost + 3% Panchagavya foliar spray at 30 and 45 days after transplanting recorded higher physical characteristics and cooking qualities of rice.
